To all t0/wm t may concern:

Be it known that ll, HARRY SIsKIN, a citi- Zen of the United States, residing at Los Angeles, in the county of `Los Angeles and State of California, have invented new anduseful llmprovements in Davenports, of which the following is a specilication.

An object of this invention is to provide a neat, simple and compact davenport having an automatic action and it comprises in combination a stationary member, an upbolstered member and an automatic supporting means comprising a leg, a brace and locking means in combination with an upholstered member of the davenport.

Said upholstered member may be the seat member or a back member, and the davenport may be constructed with an upholstered seat 'member or with such seat member and also a back member.`

The leg is designed to be applied to the end rails of the folding seat frame and is of a right `and left nature, all of the parts, however, being duplicates and the right and left characters being due to the assembling' of the parts; while the seat-back supportl is applied centrally of the davenport.

heapness, simplicity, easeof manufac ture and assembling are other objects of the invention.

`The accompanying drawings illustrate the invention Figure 1 is an end elevation illustrating i the novel supporting means in the formof an automatic folding leg applied to an open .davenport bed, solid lines indicating parts l in the supporting position of the leg, dot and dash lines indicating the parts in a folded position of the leg and dotted lines indicating the parts in positions they would occupy just previous to collapse of the leg.

liig. 2 is a fragmental end elevation of the elements in Fig. 1 showing the positions of parts when the bed is closed.

Fig. 3 is a fragmental plan view of Fig. 1.

Fig. l is an end elevation partly in section l on line L-w, Fig. 5, illustrating the novel supporting means as applied to the swinging' seatback of a davenport, the folding seat being shown in closed position. Solid lines show the seat-back and parts in open position while dot and dash lines indicate parts in closed position.

Fig. 5 is a fragmental front elevation viewed from line m5-", Fig. l showing the seat-back in open position corresponding to solid lines of Fig. a.

The foldable leg comprises an upright or standard 1 made, for example, of a straight piece of strap iron perforated withholes 2, 3, to receive pivots l, 5; a securing plate 6 pivoted by a pivot l to the top of the leg; and a locking brace 7 of strap iron, for example, pivoted by the pivot 5 to the standard 1. `Said brace 7 is provided with an angle or l.shaped slot having a long longitudinal limb 8 and short transverse limb 9 in which a pivotal headed locking pin 10 slides from one limb to the other, said pin shiftably securing a second fastening plate 11 to the brace 7. Said fastening plates 6 and 11 are provided with holes 12 and 13 respectively through which screws 14C, or the'like, may be inserted to secure the fastening plates to the upholstered reversible l davenport member or seatframe 15 which is hinged at 16 to one edge of the stationary member or frame 17 that stands on the floor.

The distance from the pivot 4- of the standard to the pin 10 is the same as the distance from said pivot to the short transverse limb 9 and the distance from the pivot pin 5 of the brace to the transverse limb 9 is the same as the distance from said pivot 5 to the pin 10 when the standard is vertical or substantially normal to the reversible frame 15 as in the solid line position A and dotted line position B, Fig. 1.

Lines a c connecting the pivot 5 to the pivot 4 to the pin 10 and the pin 10 to the pivot 3 respectively together form, when the leg is unfolded as in solid lines, Fig. 1, a right-angled triangle of which c `is the short side or base, the long side or altitude, and c the hypotenuse.

rllhe transverse limb 9 of the slot extendsv from the longitudinal limb 8 toward the altitude line b.

The pivotal pins 4, 5 and 10 are in paral lelism with the hinge pin at 16; said leg 1 and the locking brace l both being pivoted to the end of the reversible seat section 15, the leg being pivoted of the seat section, and the brace being piv- `oted at l0 to the seat section between the locking pivot l and the hinge pivot at 16, so that when the seat section is moved `from lts inverted position A, shown in solid lines at lnear the free edge .position A the force of into the slanting position C above the stationary frame or base 17 that stands upon the floor, the weight of the leg 1 and of the brace 7 will operate to close the leg automatically by gravity and bring the parts into the position C; and vice versa, as the seat is opened from the closed position, the weight of the-leg and brace will bring these parts into the locking position shown in solid lines in Fig. 1. 1t is thus seen that the necessity of manipulating the leg 1 or the brace 7 in the operation of opening and clos inthe davenport is avoided.

he whole effect of the foregoing construction is that when the reversible seatframe 15 is swung rearward from position B toward position C (see Fig. 1) the slotted end of the brace 7 is caused to swing rearward relative to the frame 15 so that the transverse limb 9 will disengage the pin 10, whereupon the brace 7 will be shifted endwise by the force of gravity and the standard 1 will swing downward alongside the frame 15, thus causing the parts to assume the positions shown at C; and furthermore, when the frame 15 is swung forwardfrom the position C or D toward the gravity will cause the standard 1 to swing forward, thus pulling the brace 7 endwise until the transverse slot 9 comes adjacent the pin 10, whereupon the force of gravity will swing the slotted end of the brace 7 downward to cause said transverse limb to engage the pin and thus lock the leg in extended or unfolded position.

The space between the pivot 5 and pin 10 increases and decreases as the standard 1 is moved toward and from a position normal to the member 15.

From the foregoing it is now clear that to open the davenport bed the attendant will grasp the reversible frame 15 and swing the same forward on its hinge 1G from the closed position shown at D to the extended position shown at A, thus causing the legs to be extended as abovey described without it being necessary for the attendant to manipulate in any way or even touch any of the parts of the legs.

To close the davenport bed the attendant will reverse the operation just described so as to bring the parts to folded positions shown in Fig. 2.

It is noted that the fastening plate 11 is somewhat thicker than the plate 6 so as to form a stop or rest upon which seats the standard 1 when the parts above described are folded as in Figs. 2 and 4:, and so as to form a spacing block to locate the brace in a plane parallel with the standard and outside of thestandard, so that the parts will swing without binding, scraping and shearing and so that when folded the brace which is held at both ends, forms a cage for the standard which is otherwise only at one end, and for the purpose of producing this cage, among other purposes, the brace is cut to approximately the same length as the standard, so that the locking pin will be located near the free end of the folded standard.

The support for the swinging upholstered seat back member 18 of the davenport (sce Fig. 1) comprises a bracket 19 on the inside of said member adjacent the top hinge 2() and a supporting brace 21 pivoted to said bracket by pivot 22. The brace 21 is similar in construction to the locking brace 7 and has the L-shaped slot with the long longitudinal limb 23 and short transverse limb 24 in which slot a pivotal headed pin 25 slides from one limb to the other, said brace 21 being shiftably secured by the pin 25 to Va fastening plate 26 on the central upright partition 27 of the storage chamber 2S which is arranged in the davenport rearwardly of the member 18 when said member is in seat back position, the member 18 forming a cover for said chamber.

When the seat back 18 is opened from the dot and dash position to the solid line position in Fig. a, the pivot 22 raises the supporting brace 21 until the transverse limb 24 of the slot comes adjacent the pin 25 whereupon gravity will swing the lower end of the brace forwardly and downwardly to cause said transverse limb to engage the pin 25 and thus lock the supporting brace 21 in position to support the seat back in open position.

To lower the seat back, the attendant will thrust the brace rearwardly, causing the pin 25 to ride out of the limb 24 and into the limb 23 whereupon the seat back is free to descend.

This construction of the seat back support is particularly advantageous in that the supporting brace may be folded up in the chamber 28 alongside the partition 27 and thereby obscured when the seat back is down while when the seat back is locked up in raised position the supporting brace 21 extends aslant rearwardly and downwardly so as to cause minimum obstructive effect when arranging bed clothes upon the open davenport.

1 claim:

The combination with the reversible 1n cmber of a davenport or the like, of a standard provided at one end with a pivot, a plate to fasten the pivot to the reversible member,l a brace pivoted at one end to the standard and provided at its other end with a slot having longitudinal and transverse limbs, and a second plate fastened to the reversible member and provided with a pin designed to engage the longitudinal limb when the davenport is open and to engage the transverse limb when the davenport is closed, said second plate being thicker than the rst plate to form a rest for the standard when the davenport is closed, the brace being suhstantially as long as the standard and outside of the standard so that the brace forms a cage for the folded standard.

my hand at ln presence of- Bope ol' thm patent may be .obtained for ve cents each, by addressing' the Washington, D. C.

In testimony whereof I have hereunto set Los Angeles, California7 this 13th clay of January, 1915.
